Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

With the continuous development of technology, there are more and more terminals available for users to choose from, such as mobile phones, tablet computers, and e-books. Users can also easily perform operations such as transfer and payment through the terminal, so the security of the terminal becomes particularly important.

Since most terminals currently provide users with touch screen control, the user can control the terminal through, for example, a finger touch operation on the display screen of the terminal. Therefore, the present invention generates preset operation information by collecting the user's habitual operation on the terminal, and when the user generates a new trigger operation on the terminal, by combining the newly generated trigger operation with the pre-generated operation information (that is, the preset operation information ) to compare, can quickly determine whether the user operating the terminal is an illegal user, and avoid the loss of legal user property and other aspects.

In order to elaborate the technical solution provided by the present invention, an embodiment of the present invention first provides a terminal control method. As shown in FIG. 1 , the method may include the following steps:

In step S110, a trigger operation of the user on the touch screen of the terminal is acquired.

The trigger operation refers to a touch operation performed by the user on the touch screen of the terminal, for example, operations such as clicking, sliding, or dragging by the user on the touch screen of the terminal with a finger. Since the touch screen of the terminal is equipped with a sensor, when the user generates a trigger operation on the touch screen of the terminal, the sensor on the touch screen can acquire the relevant operation of the user on the touch screen.

In step S120, the operation information generated by the trigger operation on the touch screen of the terminal is extracted.

The user's trigger operation on the terminal touch screen can generate a lot of information, such as sliding track, pressing force, click rate or real-time contact area area of the user's finger on the terminal touch screen, etc. In this embodiment, the present invention needs to extract The operation information required in the trigger operation is verified through the following verification of the operation information, and then it is judged whether the current user is an illegal user.

In step S130, it is determined whether the operation information matches the preset operation information.

When the operation information does not match the preset operation information, in step S140, the terminal is controlled to enter a locked state.

The preset operation information is the operation information included in the user's previous triggering operation on the terminal touch screen, that is, the user's habitual operation on the terminal touch screen. The operation information is compared to determine whether the user's current operation information matches the preset operation information. In addition, the user's habitual operation information may also be used as the standard operation information, and the operation information generated by the user's current touch-screen operation of the terminal is matched with the standard operation information.

When the operation information generated by the user touching the screen of the terminal does not match the preset operation information, it is very likely that other illegal users are operating the terminal. At this time, in order to avoid potential security risks to legitimate users in terms of property and other aspects, it is necessary to control the terminal. Enter the locked state to prevent illegal users from further operations on the terminal.

The terminal control method provided by the present invention obtains the trigger operation of the user on the touch screen of the terminal, extracts the operation information generated by the trigger operation on the touch screen of the terminal, and then judges whether it matches the preset operation information according to the operation information. When the operation information does not match the preset operation information, it indicates that the user operating the terminal is likely to be an illegal user. At this time, it is necessary to control the terminal to enter a locked state to prevent illegal users from performing illegal operations on the terminal and prevent legal users from causing property, etc. loss in terms of.

In order to describe in detail how to determine whether the operation information matches the preset operation information, as a refinement of the method in FIG. 1 , in another embodiment provided by the present invention, as shown in FIG. 2 , the operation information includes an interaction track, step S130 Can include the following steps:

In step S131, the sliding track is matched with the preset sliding track to obtain the matching degree between the sliding track and the preset sliding track.

When users control the terminal through the touch screen, they often need to perform sliding operations on the terminal. For users, for example, when they need to call the drop-down menu on the terminal screen, the general user is used to sliding the terminal touch screen with the thumb. , and perform related operations, and because the same user's palm area and finger length are constant, and the user's habitual way of holding the terminal, the user generally performs the same sliding operation, and the sliding track generated on the terminal touch screen each time Consistent. Therefore, whether the user's operation information matches the preset operation information can be determined by the user's sliding track on the touch screen of the terminal.

In step S132, it is determined whether the matching degree is less than a first preset threshold.

When the matching degree is less than the first preset threshold, in step S133, it is determined that the operation information does not match the preset operation information.

Exemplarily, with reference to FIG. 3, a two-dimensional coordinate system is established on the display screen of the terminal, and FIG. 3 includes the x-axis, the y-axis and the origin (0, 0). When the user performs a certain preset operation on the terminal, 100 is the sliding track of the user on the touch screen of the terminal, 200 is the preset sliding track, and the sliding track is matched with the preset sliding track, and the matching degree between the sliding track and the preset sliding track can be 100 and 200 on the touch screen of the terminal. If the two are completely coincident, then the matching degree is 1; if there is no overlap at all, then the matching degree is 0; if 100 and 200 overlap half, then the matching degree is 0.5. When calculating the matching degree between 100 and 200, it can be obtained by calculating the ratio of the overlapping area between 100 and 200 to the area occupied by 200. For example, when the ratio of the overlapping area between 100 and 200 to the area of 200 is greater than 0.7, it is determined that the operation information does not match the preset operation information.

In order to describe in detail how to determine whether the operation information matches the preset operation information, as a refinement of the method in FIG. 1 , in another embodiment provided by the present invention, as shown in FIG. The real-time pressing force value generated on the above, step S130 may include the following steps:

In step S134, the average pressing force value generated by the user on the touch screen of the terminal is calculated according to the real-time pressing force value.

Exemplarily, when the user performs a sliding operation on the touch screen of the terminal, a continuous pressure is generated on the touch screen of the terminal, and the force value generated by the pressing cannot remain unchanged during the sliding operation. The real-time compression force value generated on the screen.

In order to simplify the calculation, some values can be sampled from a series of obtained pressing force values, and then the average value of these values can be obtained to obtain the average pressing force value.

In step S135, the absolute value of the pressing force difference between the average pressing force value and the preset pressing force value is calculated.

The difference between the average pressing force value and the preset pressing force value is calculated, and then the absolute value is obtained to obtain the absolute value of the pressing force difference between the average pressing force value and the preset pressing force value.

In step S136, it is determined whether the absolute value of the pressing force difference is greater than a second preset threshold.

When the absolute value of the pressing force difference is greater than the second preset threshold, in step S137, it is determined that the operation information does not match the preset operation information.

If the absolute value of the difference in pressing force is greater than the second preset threshold, it means that the difference between the average pressing force and the preset pressing force is too large, and it can be determined that the operation information does not match the preset operation information.

In order to describe in detail how to determine whether the operation information matches the preset operation information, as a refinement of the method in FIG. 1 , in another embodiment provided by the present invention, as shown in FIG. 5 , the operation information includes: The real-time sliding rate generated on the screen, step S130 may include the following steps:

In step S1371, the average sliding rate generated by the user on the touch screen of the terminal is calculated according to the real-time sliding rate.

Under normal circumstances, when the user performs a sliding operation on the terminal touch screen, the rate starts to increase from 0, and then gradually decreases to 0 after reaching a peak value. Therefore, it is necessary to obtain the real-time sliding rate of the user on the touch screen of the terminal. In order to simplify the calculation, the obtained real-time sliding rate can be sampled, some values are extracted from the obtained real-time sliding rate, and the average value of these values is calculated as the average sliding rate.

In step S1372, the absolute value of the speed difference between the average sliding speed and the preset sliding speed is calculated.

The difference between the average sliding rate and the preset sliding rate is obtained, and the absolute value of the difference is obtained as the absolute value of the rate difference between the average sliding rate and the preset sliding rate.

In step S1373, it is determined whether the absolute value of the rate difference is greater than a third preset threshold.

When the absolute value of the rate difference is greater than the third preset threshold, in step S1374, it is determined that the operation information does not match the preset operation information.

If the absolute value of the rate difference is greater than the third preset threshold, indicating that the difference between the average sliding rate and the preset sliding rate is too large, it can be determined that the operation information does not match the preset operation information.

In order to describe in detail how to determine whether the operation information matches the preset operation information, as a refinement of the method in FIG. 1 , in another embodiment provided by the present invention, as shown in FIG. The click frequency on the above, step S130 may include the following steps:

In step S1381, the absolute value of the frequency difference between the click frequency and the preset click frequency is calculated.

Exemplarily, when the user double-clicks or triple-clicks the terminal touch screen, since different users may have different clicks on the terminal touch screen, the frequency of the user's click on the terminal touch screen can be obtained, and then the The difference between the click frequency and the preset click frequency is obtained to obtain the difference, and then the absolute value of the difference is obtained as the absolute value of the frequency difference between the click frequency and the preset click frequency.

In step S1382, it is determined whether the absolute value of the frequency difference is greater than a fourth preset threshold.

When the absolute value of the frequency difference is greater than the fourth preset threshold, in step S1383, it is determined that the operation information does not match the preset operation information.

If the absolute value of the frequency difference is greater than the fourth preset threshold, it means that the difference between the user's click frequency and the preset click frequency is too large, and it is likely that an illegal user is operating the user's terminal. The set operation information does not match.

In order to describe in detail how to determine whether the operation information matches the preset operation information, as a refinement of the method in FIG. 1 , in another embodiment provided by the present invention, as shown in FIG. 7 , the operation information includes the inclination of the terminal. Steps S130 may include the following steps:

In step S1391, the absolute value of the inclination difference between the inclination and the preset inclination is calculated.

With reference to Figure 8, taking the terminal as a mobile phone as an example, at present, acceleration sensors are basically installed on mobile phones, and a three-dimensional coordinate system in the three directions of x, y and z is established on the mobile phone. The components in the three directions of and z, when the mobile phone is in a state of no acceleration (such as when it is stationary or in a state of uniform linear motion), only the acceleration of gravity will be decomposed into three coordinates of x, y and z.

The inclination of the mobile phone can be understood as the angle between the mobile phone screen and the horizontal plane. As shown in Figure 8, since the z-axis is perpendicular to the mobile phone screen (the angle is 90°), and the angle between the z-axis and the horizontal plane, the mobile phone screen and the horizontal plane Then the angle between the mobile phone screen and the horizontal plane can be obtained by calculating the angle between the z-axis and the horizontal plane, and the angle between the z-axis and the horizontal plane can be obtained according to the data detected by the acceleration sensor, so it can be easily Calculate the tilt of the phone.

In step S1392, it is determined whether the absolute value of the gradient difference is greater than a fifth preset threshold.

Since each user has his own habit of operating the terminal, generally the user holds or places the terminal at a certain inclination. Therefore, whether the user is an illegal user can be determined by judging the inclination of the terminal when the user uses the terminal.

When the absolute value of the gradient difference is greater than the fifth preset threshold and greater than the fifth preset threshold, in step S1393, it is determined that the operation information does not match the preset operation information.

If the difference between the inclination of the terminal and the preset inclination is too large, the current user using the terminal is likely to be an illegal user, and it can be determined that the operation information does not match the preset operation information.

As a refinement of the method in FIG. 1, as shown in FIG. 9, after step S140, the method may further include the following steps:

In step S150, the user is prompted to input the identity authentication information, so that the terminal authenticates the identity authentication information input by the user after acquiring the identity authentication information input by the user.

When the terminal enters the locked state, an information input box can be popped up on the display interface of the terminal, so that the user can input the identity authentication information in the information input box, so as to prevent the user from changing the operation habit and using the user to use the terminal normally. The identity authentication information may be a security password, which is reserved by the user. This password is different from the login password and payment password. Even after the login password and payment password of the user are stolen, the security password can still be used for A secure password authenticates the user's identity.

It should be noted that the above-mentioned embodiments can be combined with each other. For example, one or more combinations of the above-mentioned user's sliding trajectory, real-time pressing force value, real-time sliding rate, click frequency or mobile phone inclination can be judged respectively. operation to be judged. For example, when the above judgments do not meet the conditions at the same time, it can be indicated that the user is an illegal user, and after further verification and passing the identity of the user, the terminal can continue to be operated to avoid losses such as property caused by the user. Of course, various factors for the above judgment can be set according to specific conditions, and the user can be judged whether it is an illegal user by selecting the required combination, and the present invention is not limited to this.

The terminal control method provided by the present invention obtains the trigger operation of the user on the touch screen of the terminal, extracts the operation information generated by the trigger operation on the touch screen of the terminal, and then judges whether it matches the preset operation information according to the operation information. When the operation information does not match the preset operation information, it indicates that the user operating the terminal is likely to be an illegal user. At this time, it is necessary to control the terminal to enter a locked state to prevent illegal users from performing illegal operations on the terminal and prevent legal users from causing property, etc. loss in terms of.

In addition, one or several combinations of the user's sliding trajectory, real-time pressing force value, real-time sliding rate or click frequency can be used to judge the user's current operation. If the judgment does not meet the conditions, it is likely to indicate that the terminal is currently operating. The user is an illegal user.
